^ The optics is just really unique, and definitely different than regular zoomies. Of course, a lot of marketing etc etc, and the output is just laughable these days. Nevertheless I like Led Lenser; both appearance as well as the optic is very classic and timeless like a Maglite.
I’ve always been fairly indifferent towards optics, so maybe I fell for Led Lenser’s advertisement. The optic has properties of both a lens and a reflector. I thought they actually developed this themselves. I think it’s pretty cool what they did.
No it’s not, it’s different because the focal point of the lens and reflector is farther back which allows the LED to be slid forward such that only the center lens collects light from the LED.
This is what allows their zoomies to have almost perfectly even flood and then also zoom to have a circular spot that uses the full area of the optic (for highest possible lux)
99% of TIR flashlights are fixed lens, and the TIR provides a mix of spot and flood just like a normal reflector.
The few focusing TIR flashlights that exist are either like the fenix flashlights (that only widen the beam, not narrow it) or cheap led lenser clones which are noticeably worse at focusing.
It is just a TIR though, only they make it slide to zoom.
With the wide beam you basically only use the lens, close to the emitter (as you said).
There are rather similar TIRs on the market that could do the same, but usually they’re not narrow beam TIRs or have frosted surfaces (inside the LED cavity).
(AFS = Advanced Focus System, P = Power, BM = Blue Moon)
P3 AFS P: This one delivers 75 lumens. Very nice, but dang I wish it had a lower ~5 lumen mode as well.
P3 AFS: This one delivers something like ~20 lumens. For a 1 mode light this is actually more practical than the Power version.
P3 (regular), or P3 BM : This is absolute junk. This one doesn’t use the Led Lenser optic, instead it’s a regular lens resulting in a terrible beam. Led is also terrible. It’s called Blue Moon, because the circumference of the beam is blue in colour.
I believe Led Lenser is like Surefire and Maglite; they have their own market so to speak. Furthermore, the P3 models are fairly old models as well. I’d say a proper AAA light puts out a maximum of 120 lumens. This is visually comparable to 75 lumens. But yeah, it’s not about the latest and greatest when it comes to Led Lenser.
My chain key light is still the original Nitecore Tube. Very low output and fairly bad tint, but it really fulfills my needs… I think this is also how you should approach Led Lenser models. They produce “enough” light.
The point is that you can’t get a TIR like it anywhere else.
Even the coast flashlights that have very similar technology can only partially zoom into a spot.
The only other flashlights that can switch between smooth flood and tight spot are pure lens flashlights, which lose a ton of efficiency when zoomed in.
Yes, the benefit of a TIR is obvious.
I have 2 fake Led lensers, one without brand and a Pop lite.
The latter wasn’t even that cheap…
But it had the problem of not enough head travel.
So i wasn’t able to get to full flood nor to full focus…
And as you may know, even the real Led Lensers are not ideal (ringy) in between full focus and full flood…
So it was a disappointing light.
The other one, which was only 10 bucks, is much better.
(like many of my lights, they’re both taken apart to be modded… some day…)
You can take a fixed reflector light and put a zoomable lens inside it (somehow).
So when you want flood, you bring the lens closer to the LED, which will use the light that would otherwise be reflected by the reflector, and act like a zoomed out zoomie.
For throw, you move the lens forward so it focuses the light that would otherwise be spill.
I’ve seen this on this forum somewhere, can’t remember where though, but likely in Argo’s zoomie thread.
No, that’s what I orignially though, but take a look at the tests and reviews of those flashlights, when you focus them you get something that looks like this:
Not a 100% spot like with led lenser.
The flood mode is basically the same though, even brightness with an outer ring.
They’re not really meant to be used in between flood or spot modes, but depends on the model there may be more or fewer rings.
It’s not bad actually, on pretty much all lights you can unfocus it enough to give a larger spot with no visible rings or spill but a lot more area than fully focused.
I think I’ve used about 7 different Led Lensers so far.
